A system and a method to communicate operating capabilities in a telecommunications network.
In general, the present invention will be refers to a system and a method to communicate capacities of operation in a network or telecommunications networks.
In one aspect, the present invention relates to to a method of negotiating operating capacities between telecommunications subscribers and more particularly refers to a method of enabling codec compatibility between a first mobile station of a public land network of mobile terminals (PLMN) and a node of network, located in a network of fixed terminals or in a PLMN different or in the same PLMN, although it is appreciated, however, that the invention is not limited to its use, only, in that application.
In another aspect, this invention relates to a method of providing operational capabilities in a node a telecommunications network and, more particularly, it refers to a method of providing operational capabilities in a node of a telecommunications network during a procedure call establishment between a mobile station in a network of Telecommunications between mobiles and a network element.
In general, when a subscriber who has a mobile station (MS) or a terminal located within a first PLMN want to contact another subscriber that has a mobile station or terminal located in a PLMN different, the first subscriber mentioned MS must transmit to his Service Switching Center (MSC) in English) operating capabilities, such as, a codec or a list of codecs on which you can transmit information or posts. The negotiation must begin, then, typically, on a switched network between fixed terminals, such as the PSTN, or ISDN, IP or ATM, with the other mobile station or terminal. Once I know have negotiated the operating capacities between the two mobile stations, then the call can continue to use those capacities All this negotiation needs a lot to be done signaling between the originating mobile station and its service MSC every time you need to establish a call.
Since mobile networks are being increasingly advanced and require the transmission of older amounts of data between network nodes or through other networks such as the PSTN or ISDN fixed terminal network, this produces on the network nodes the burdensome task of trying all data. In addition, the signaling procedure occurs with relative slowness It would be desirable, therefore, to delete data extraordinary, where possible, especially between an MS and your service MSC, to increase signaling speed and reduce the signaling load between the MS and the MSC, especially, for example, in the establishment of the call. By reducing the amount of signaling data that it needs to be transmitted between a mobile station of origin and its MSC service, network resources could be used in a way more efficient.
In a particular provision, developed by the current applicant, a protocol independent of Carrier Independent Call Control (BICC, in its acronym in English) to negotiate operating capabilities and, in particular, the negotiation of codecs. The BICC protocol It is particularly suitable for networks between third-party mobiles generation, such as the UMTS, in which technologies are used of transport other than TDM. However, the negotiation BICC codecs proposal is not fully optimized For mobile environments. In particular, it is not optimized for quick selection of operating capabilities for calls mobile phones when, for reasons of efficiency, transcoders are located at the edge of the core network in GMSC.
US 5638412 describes a method and a system for negotiating regime and service in a digital communications system between a mobile station and a base station WO 98/36605 addresses communication inverse of the call service capabilities of the station mobile. After a request for updating capabilities, the mobile station sends information concerning the services of call supported by the mobile station to a switching node of service that uses an update response message from capabilities via the Fast Associated Control Channel (FACCH, in its acronym in English). The information received is stored in the node of service switching.
The present invention seeks to overcome or improve substantially at least one of the disadvantages of the prior art
In one aspect, the present invention provides a method according to independent claim 1.
In another aspect, the present invention provides a telecommunication system according to claim independent 7.
Essentially, the present invention is consequence of the understanding that the network resources of Mobile telecommunications can be used with more efficiency by maintaining station attributes mobile or operating capabilities on a network node associated with the mobile station. Preferably, the network node is a Register of Visitor Positions, VLR in their acronym in English. Additionally, the network node can be a Register of Domestic Locations, HLR in its acronym in English, a Mobile Switching Center, MSC in its acronym in English, or a Switching Center between Mobile Gateway, GMSC in its acronym in English. Particularly, the invention can provide creating a list of operating capabilities on a node network upstream of the mobile station. Having done this, a comparison of this list with another list received from an item remote telecommunications to negotiate the capabilities of operation in the establishment of calls is achieved without involve communication resources between the station Mobile and network node.
In another aspect, the present invention seeks substantially overcome or improve any of the disadvantages above providing a method of negotiating capacities of operation between a mobile station and a network node in which the amount of signaling required between the station is reduced originating mobile and its service MSC.
Therefore, in this respect, the present invention provides a method of negotiating capabilities of operation between a mobile station in a network of telecommunications between mobiles and a network node, in which said mobile telecommunications network includes means of storage associated with a switching center that serves said mobile station;
The method includes the operation of:
- transmit a list of one or more operating capacities from said mobile station to the switching center to store in said storage media as part of a signal that is not based in a call
The method may also include the operation of update said storage media with another list of operating capabilities, such as codecs, for use by said mobile station when said mobile station travels from a position area to another position area, sending a message to said switching center for subsequent storage in Storage media The message can be a message from position update or any existing message or new.
The network node can be located in a network of fixed terminals, such as PSTN or ISDN or in a network of mobile terminals, or a mobile station located at another telecommunications network between mobiles.
The capacity or operating capabilities can be prioritized so that a list of capabilities Preferred operation is supplied by the mobile station. Operating capabilities may include algorithms of security, or codecs, in which case the storage media they will receive the list of algorithms supported by the MS for the subsequent storage.
Therefore, the signaling load is reduced between the MS and the MSC in establishing the call as the operating capabilities of the MS are already stored in the storage media associated with the switching center and the MS does not need to transmit the operating capabilities every Once you need to establish a call. In addition, the MS does not need receive the list of operating capabilities in the message of establishment from the switching center every time you receive a call.
In yet another aspect, the present invention seeks substantially overcome or improve any of the disadvantages above providing a method of making available the list of operating capacities to be used between a station mobile and a network node during an establishment procedure of the call between the mobile station and the network node. By consequently, in this aspect, the present invention provides a method of providing operating capabilities of a station mobile in a node of the telecommunications network to an element of telecommunications during the establishment procedure of a call between the mobile station and said element of telecommunications, and in which said telecommunications element transmits a list of telecommunication networks to the node operating capabilities of the telecommunications element As part of the call establishment procedure, the method includes the operations of:
convey a list of capabilities of operation of said mobile station from a center of switching serving said mobile station to said network node of telecommunications;
provide such list of capabilities of operation in said node of the telecommunications network;
so that at the initiation of a communication from said network element to said mobile station, said node of the telecommunications network selects internally one or more operating capabilities common to the mobile station and to the network element.
In this way, the invention accelerates advantageously the selection of operating capacities for calls terminated from mobile terminals where the negotiation on the operating capacities that are going to use between the mobile station and the network node is no longer required during call establishment.
The network element is preferably another mobile station, but it can be, as an alternative, a device terminal or a telecommunications node. The list of capabilities of mobile station operation can be transmitted to the node of the network in response to a recovery message from the information sent from the network node to the center of commutation. The list of operating capabilities of said mobile station may have been previously stored in some storage media, such as a VLR, associated with the center switching that serves the mobile station. The network node of telecommunications can be a node located in the same network of telecommunications or PLMN, such as the mobile station. Network node telecommunications can be a node located in a network of fixed terminals to be crossed when establishing a call between the element of the network and the mobile station. As an alternative, the node of the telecommunications network can be a node of a network different from that in which the mobile station is located, and is preferably in the home network of the mobile station. The node, when it is located in one of the PLMN, it is preferably a GMSC The list of operating capabilities of the element of the network and mobile station can be prioritized in the sense of that the preferred operating capacities are specified, such as codecs.
A list of operating capabilities of the network element can be stored in a node of the network that it serves the network of said network element. Preferably during the establishment of the call, the list of capabilities of network element operation is transmitted from the node from the network that serves the network of the network element, to the node of the telecommunications network
Therefore, the selection of capacities of operation to be used is accelerated between the station mobile and the network element by the previous storage of the list of operating capabilities in the network node of telecommunications The negotiation of the capacities of codec operation does not need to occur during part of the establishment of the call between the mobile station and the network element since the specific operating capabilities, such as the codecs to be used, can be automatically selected by the network node of telecommunications
A preferred embodiment of the invention will be described below, only by way of examples, making reference to the drawings in which:
Figure 1 is a schematic diagram of a telecommunications system used in accordance with this invention;
Figure 2 is a signaling diagram that shows the signaling messages that are exchanged between two mobile stations in the telecommunications system of the Figure 1, according to a first embodiment of the present invention
Figure 3 is a signaling diagram that shows signaling messages that are passed between a station source mobile and a destination mobile station using the system of telecommunications of figure 1 according to a second embodiment of the present invention;
Figure 4 is a signaling diagram of the second embodiment of the present invention, which shows messages signaled between a switching center that serves a destination mobile station and a node of the network telecommunications, which is, in this case, a GMSC located in a home network of the destination mobile station.
In general, the present invention provides operating capabilities of a mobile station in a node the network capable of storing operating capabilities and, afterwards, the negotiation of the operating capacities can continue with a remote telecommunication element in which the negotiation does not need to occur between the mobile station and the node, which is upstream of the mobile station. When negotiating the operating capabilities, a stored list is compared to the operating capabilities of the remote element, which can be provided, also, before the establishment of the call and stored in a node upstream of the remote element. Preferably, in negotiating the capabilities of operation, a selection is made based on the capabilities of operation common to both lists of capabilities of operation stored in each node. Preferably, the Remote telecommunication element is another mobile station, a terminal device or a node.
In figure 1, a first is shown mobile station 4 in a position area 6 (LA1), of a first PLMN 2, which is controlled by controller 8 of the station base. The switching center between mobiles 10 is in communication with each of the BSC 8 and with an additional BSC 9. The MSC 10 has associated storage media in the form of a Register of Visitor Positions (VLR) 12 in which they are stored details of mobile subscribers and their units phones that are temporarily located within your area of service, in this case LA1 and LA2. An MSC Gateway (GMSC) 14 provides an interface between other networks such as PSTN or ISDN 16. Additional storage means 18 in the form of Domestic Positions Registry (HLR) provide storage permanent subscriber details and keep track continuous of a subscriber's position if that subscriber is in an area of service of the MSC or in a different PLMN. This information is used by GMSC 14 when receiving a call from another network. The PLMN 2 also has other MSCs, such as MSC 20 with its own VLR 22, and whereby MSC 20 serves BSC 24 and 26.
When MS 4 wishes to contact another mobile station 28 located in another PLMN 30, a message from Call setup will be transmitted from MS 4 to your MSC 10 service. After this, the negotiation of capabilities of operation, such as codecs or security algorithms, takes place between MSC 10 and PLMN 30 and, particularly, an MSC 29 that is serving between MS 28. An address message Initial (IAM) is used for signaling between MSC 10 and MSC 29 of PLMN 30. Negotiation continues to occur, and when a capacity for operation between MS 28 and MS 4 to transmit the data, Then such data can be transmitted.
The MSC 10 or, equivalently, a node of Carrier Independent Call Control (BICC, in its acronym in English) has the ability to separate the ISUP signal in a part of Call Control (CC) and a part of Carrier Control (BC), in which the call control part of ISUP carries the message Initial Address (IAM).
According to the present invention, the MS 4 regularly transmits to its service MSC 10, via a message, such as a position update message or any other existing or new message, a list of operating capabilities -applicable to the MS 4 which is subsequently stored in VLR 12 associated with that MSC. The list of operating capabilities can be updated at predetermined times, for example, during the polling performed by the service MSC 10 or when the mobile station 4, for example, changes its position area, say from LA1 to LA2. Alternatively, a special procedure can be established between MS 4 and MSC 10 / VLR 12 to update capabilities. Then, the updated list of operating capabilities is subsequently stored in VLR 12 associated with MSC 10. In doing so, the negotiation is managed between MSC 10 and MSC 29 since there is a compatible operating capacity between them in which both mobile stations 28 and 4 can communicate. The MSC that controls the MS 4 and the MS 28 knows the operational capability options that each MS can support and the MSCs handle the negotiation on behalf of the MS. Equivalently, the MS 28 has a list of operating capacities stored in the VLR 31 that it can use. In doing so, this creates less signaling in the establishment of the call, for example, between MS 4 and MSC 10, and between MS 28 and MSC 29. In practice, when an MS 4 requires initiating a call, the MSC 10 will automatically select an operating capacity from the list of operating capacities stored in the VLR 12, and then subsequent negotiation occurs between the MSC 10 and the MSC 29. The updated list of operating capacities may be in order of priorities, so if the preferred operating capacity
cannot be negotiated, then compatibility with the next preferred operating capacity is attempted.
The IAM that originates from the service MSC 10 of MS 4, includes the list of operating capabilities that the source MS 4 prefers to use, and once an ability to operation is agreed by the BICC node 29 that serves the receiving or destination MS 28, then the receiving MS 28 will respond by node 29 which confirms using the ability to selected operation.
If MS 4 crosses to another LA3 position area, then the VLR 22 associated with the MSC 20 supervising the BSC 24, which in turn supervises the LA3, will be updated with the new temporary records of the MS, 4 as well as the HLR 18. Therefore, any negotiation that will occur at the beginning of a call from a mobile station 4 when in the zone of LA3 position will be done by VLR 22, and VLR 31 of the subscriber of termination, like the new VLR 22, will have the list of capabilities of updated operation.
An example of signaling that occurs between mobile stations during call set-up is shown in Figure 2. MS 4 of PLMN 2 initiates a call set-up message at 40. This is received at service MSC 10 at that an Initial Address Message (IAM) is transmitted by way of example over the core network 16 to the MSC 29 serving the MS 28 of the terminating subscriber. The IAM signaling is shown in 42. The IAM contains a list of operating capabilities, which can be prioritized, over which the MS 4 can transmit. The establishment message 44 is used for signaling between the MSC 29 of the terminating subscriber and the MS 28. The MS 28, then, through its service MSC 29, responds by the MSC 29 negotiating or providing a list of operating capacities on which MS 28 can transmit to MSC 10 in operation 46. An update can be transmitted in several instants or occasions from MS 28 to VLR 31 in 45. The negotiation then occurs in 47 between MSC 10 and MSC 29. Once an agreement has been reached on which operating capacity is to be used between mobile stations 4 and 28, at 48, a bell signal is initiated and an alert message is sent at 50 and then the MSC 29 serving the MS 28 sends a full address message at 52 to the MSC 10. The MSC 29 also sends a call progress message at 56 in response to the reception of the warning message. On receiving this message,
An ALERT message is sent in 54 to MS 4 which responds by generating a ring tone.
If the subscriber of MS 28 responds, that terminal send a connection message in 58 which in turn is recognized by your service MSC that sends a reply message in 60 to MSC 10 which, in turn, sends a connection message 62 to MS 4. The conversation can occur, then, between the two mobile subscribers in 64.
It is understood that, although this embodiment has been described in relation to a GSM network, the invention is It also applies to the third generation of PLMN and other networks second generation PLMN networks that include PDC, D-AMPS, UMTS, CDMAOne and CDMA2000, which have similar architectures In the negotiations of 3G networks with respect to operating capabilities, such as codecs, it can be done through core network nodes such as the public switched network.
In addition, MS 28 of PLMN 30 can be conveniently replaced by a network node located in the PSTN / ISDN 16 fixed terminal network or in the same PLMN 30. Thus, such capacity negotiation can occur between stations phones on the same mobile network.
According to a second embodiment of the present invention, using the telecommunications system of figure 1, a network element is shown, from here on ahead, called mobile station of origin 4, located in a first PLMN 2 whose mobile station 4 is controlled by the Base Station Controller or BSC 8. A Switching Center Between Mobile (MSC) 10 directly controls or is linked to the BSC 8 and has associated storage media in the form of a VLR 12. A GMSC 14 provides an interface between other networks such such as the PSTN or ISDN 16. The GMSC 14 is directly linked to the MSC 10 and with another MSC 20 that has an associated VLR 22. Each one of VLR stores details of mobile subscribers and their units phones that are temporarily located within the service area of the associated MSC. Other storage means 18 in the form Domestic Positions Registry (HLR) provides permanent storage of subscriber details and keeps a continuous track of a subscriber's position if that subscriber is in a service area of the MSC or in a PLMN different. This information is used by the GMSC 14 when it receives A call from another network.
When the mobile station 4 wishes to initiate a communication or a call with a mobile station, hereinafter referred to as the destination mobile station, MS 28 located in another PLMN 30, a list of operating capabilities of origin MS 4 is already stored in the VLR 12 associated with the service MSC 10 of the MS 4. The destination mobile station MS 28 is served by the base station controller BSC 27 which, in turn, is linked to and controlled by the MSC 29. Associated with the MSC 29 are storage means in the form of a VLR 31 that store a list of operating capabilities of the MS 28. The MSC 29 is directly linked to a GMSC 32 which, in turn, is linked to another network such as PSTN / ISDN 16. An establishment message is transmitted from MS 4 to MSC 10. After this, an Initial Address Message (IAM) is sent from MSC 10 to GMSC 32 which can pass through other nodes such as the GMSC 14 and the fixed terminal network 16. Included in this message are the operating capabilities, which include, for example, the list of codecs that the MS 4 can use. In this reception operation by the GMSC 32 of the IAM from the MSC 10, the GMSC 32 will send an information retrieval message in the form of a recovery signal of the routing information of the MSC 29 / VLR 31 requesting the identification of the destination mobile station by the MSISDN or the IMSI, in which case the MSC 29 / VLR 31 will respond by sending the Mobile Subscriber's Roaming Number ( Roaming ) (MSRN). This is sent back to the GMSC 32 for the purpose of routing the call, and a list of supported operating capabilities of the MS 28 is returned to the GMSC 32. The GMSC 32 is then in a position to select a codec or other capabilities. of operation for use and compatibility between the source MS 4 and the destination MS 28. An additional Initial Address Message (IAM) is sent from the GMSC 32 to the MSC 29, including the selected codecs whereby a call is established between destination MS 28 and source MS 4. The list of supported operating capabilities, including codecs, by MS 28 is initially obtained from VLR 31 for use in the routing information retrieval message of return from MSC 29 to GMSC 32.
The MSC 10 or, equivalently, a node of BICC has the ability to separate a signal from the user's part of the ISDN (ISUP) in a part of Control of Call (CC) and a part of Control of Carrier (BC) to which the part of the Call Control (CC) of the ISUP leads to the address message Initial AMI. By extracting the parts of the CC and the BC via the ISUP, the part of BC can allow transmission in levels other than PCM, particularly through the network of terminals fixed 16, which works, generally, at 64 kbit / s. For example, the channels that require only 8 kbit / s or 16 kbit / s can be used so that when MS 4 communicates with MS 28, the codecs selected may reflect transmission at different levels of those of PCM, such as 13 kbit / s, for example.
Referring to Figure 3, MS 4 of the Source PLMN 2 establishes the call through signal 34 of establishment that is received by MSC 10. From there, MSC 10 sends an IAM 36 with a list of operating capabilities of MS 4, which may contain, for example, a list of X, Y codecs, Z that MS 4 can use. This is transmitted to the GMSC 32, which, at by way of example, it is transmitted over a core network 16. The GMSC 32 then sends the information retrieval message 38 from routing to MSC 29 / VLR 31 and, when that signal is received, a signal is returned to GMSC 32 including the codec list supported and other operating capabilities of the MS 28. In this particular example, these supported codecs are identified by X, Y and W. The GMSC 32 then selects a appropriate codec, in this example X, to be used by MS 4 and via MS 28, and sends an IAM 44 to MSC 29 that includes the codec enumerated X and, from there, a signal 42 of establishment from MSC 29 to MS 28. At the same time, the recovery message 38 is being sent to MSC 29, a signal 46 call handling is sent from MSC 10 to MS 4 to inform MS 4 of the progress of the call. A message 48, in the form of an application transport message (APM, in its acronym in English), which contains the selected codec X is transmitted from the GMSC 32 to the MSC 10 which, in turn, transmits another 50 progress call to MS 4 that contains the codec selected X in this case. The Carrier Access channels to the Radio (RAB) are then established between mobile stations and their respective MSCs in operations 52 and 54 respectively. An alert signal 56 is then sent from the MS 28 of destination to the MS of origin 4 as a band tone. In receiving the alert message, MS 4 responds by generating a ringtone, and if the subscriber of mobile station 28 answers, that MS sends a connection message in 58 to MSC 29. The connection is, then, recognized by the MSC 29 in a return signal 60 to the MS 28 and then the MSC 29 sends a reply message 62 to the GMSC 32, which is then sent in 64 to MSC 10. A message 66 of connection is transmitted, then, from MSC 10 to unit 4 of the MS and the connection is recognized by MS 4 on a signal 68 of return to MSC 10. After that, the conversation may have place between the two mobile subscribers.
Referring to Figure 4, the message for retrieval of routing information is sent by the GMSC 32 to the Domestic Positions Registry (HLR) 33 as a signal 70. This signal is sent using the protocol of the Mobile Application Part (MAP), and contains the information requesting the identity of the mobile subscriber 28, such as the MSISDN or the IMSI, of the HLR 33. The HLR 33 then sends a signal 72 using MAP, to the visited network, in this case MSC 29 and VLR 31 of MS 28. Signal 72 includes the request to MS 28 to provide a roaming number or an IMSI (International Mobile Subscriber Identity, meaning in Spanish) of the previous acronym). Once received by the MSC 29, it responds with a signal 74 that contains an acknowledgment of the signal 72 and transmits the roaming number of the mobile subscriber, applicable to the MS 28 together with a list of operating capabilities, which includes a list of codecs, to be used by MS 28. This list is retrieved from VLR 31. That is transmitted to HLR 33, which in turn sends a signal 76 to GMSC 32, which contains the acknowledgment of the routing information and the MSRN and the list of operating capabilities of the mobile station 28.
It will be appreciated that the list of capabilities of operation included in the IAM 36 can be incorporated into the MAP message 70 sent from GMSC 32 to HLR 33 and then in the MAP message 72 from HLR 33 to MSC 29 / VLR 31. The Selected operating capacity can be returned, then, to GMSC 32 from MSC 29 / VLR 31 via messages 74 and 76 of the MAP. In this case, codec selection occurs in the MSC 29 / VLR 31.
Although this particular realization has been described with respect to a GSM network, the invention applies to same way to third generation PLMN networks and other networks Second generation PLMN, which have similar architectures. In addition, the node of the telecommunications network in this embodiment Preferred has been identified as GMSC 32. It can also have an additional GMSC in the network identified as the network of the destination mobile station 28. Alternatively, it can be any other node in a PLMN network or in a node located in the network of fixed terminals 16. In addition, the call does not it can be established, necessarily, through a network of fixed terminals 16, but it can be from a mobile network to another network mobile or mobile station of origin and mobile station of destination It can be located within the same PLMN.
With the above description in mind, appreciate that the speed and efficiency at which the operating capabilities, such as codecs and algorithms of security, can be accelerated substantially from calls terminated from the mobile, in which a list of operating capabilities of the mobile station is stored in a selected telecommunications node, so that the need to negotiate operating capabilities outside of band, towards the mobile termination station, is reduced substantially or does not exist at all. In addition, the GMSC that gives service to the mobile station of origin may have referred to this a list of operating capabilities of the mobile station of source or network element that is sent from the designated VLR associated with the originating mobile station or network element.
